I don't know what happened, but my 3d Machine simulation stopped working. I didn't change TNG version between the working and not working state. So it must be something not directly related to the TNG version.
I just saw the 3d Visualization for a very short time after TNG start and then it was gone and I have no Idea why. Maybe i changed something in configuration, but i am unable to find the cause for the missing Machine Simulation.
May you take a look at my attached Profile to see if it's working on your side, pleace?
Meanwhile I upgradet to the last TNG version but no change. (2023.02.20)
